Through the Better Climate Challenge, the Department of Energy developed a Framework for Greenhouse Gas Emissions Reduction Planning that provides guidance to organizations seeking to reduce GHG emissions across their portfolio. The process described in this framework helps organizations develop an actionable plan that identifies solutions, prioritizes measures, and lays out a phased pathway to achieve deep emissions reductions.
An overview of this framework (2023) can be found here.

As a companion document to the framework, GHG Emissions Reduction Audit: A Checklist for Owners provides guidance on scoping building emissions reduction audits.
